Generation of sub 100 fs pulses from a diode pumped Yb:Y3ScAl4O12 ceramic laser

We experimentally demonstrate the generation of sub-100-fs pulses from a diode-pumped passively mode-locked Yb:Y3ScAl4O12 (Yb:YSAG) ceramic laser. Stable mode-locked pulses as short as 96 fs at the central wavelength of 1052 nm with a repetition rate of ~102 MHz are obtained. The laser has a maximum
